Abstract: The present disclosure provides methods and/or kits for detecting an analyte in a sample. Some embodiments provide a method for detecting a non-nucleic acid analyte in a sample using a solid substrate comprising a bound immobilization agent and an antibody capture agent and a detectable agent, which can bind to the analyte. The antibody capture agent comprises, at a plurality of sites, a ligand for the immobilization agent. A complex between the analyte, the antibody capture agent and a detectable agent is formed and immobilized on the solid substrate by binding between the immobilization agent and the ligand. In some embodiments, the ligand and the immobilization agent are a binding pair comprising a peptide tag and an anti-peptide tag antibody.

Abstract: Methods for characterizing a test subject's, particularly a human test subject's, risk of having cardiovascular disease or developing cardiovascular disease are provided. Also provided are methods for characterizing a test subject's risk of experiencing a complication of cardiovascular disease near term. The methods comprise determining levels of one or more carbamylated biomarkers in a bodily fluid of the test subject and/or comparing these levels with a reference value. In certain embodiments, the carbamylated biomarkers are carbamylated albumin, carbamylated fibrinogen, carbamylated immunoglobulin and carbamylated apolipoprotein A. In other embodiments, particularly where the test subject does not have clinical evidence of renal disease, the carbamylated biomarker is free and/or total peptide-bound homocitrulline.

Abstract: Methods and kits are provided for assessing radiation injury and exposure in a mammal. The methods comprise the steps of: obtaining one or more test samples from the mammal, contacting the test samples with an antibody immunoreactive with a citrullinated protein to form an immunocomplex; and detecting the immunocomplex with an ELISA; wherein a decrease in the quantity of the immunocomplex in the test samples, as compared to the quantity of immunocomplexes formed under identical conditions with the same antibody and a control sample from one or more mammals known to have a lower degree of radiation injury or exposure, indicates a higher degree of radiation injury and exposure to the mammal. The information obtained from such methods can be used by a clinician to accurately assess the extent of radiation injury/exposure in the mammal, and thus will provide a valuable tool for determining treatment protocols on a subject by subject basis.

Abstract: The inventors have proposed a novel panel of human serum protein biomarkers for diagnosing hepatic fibrosis and cirrhosis. Presently there is no reliable non-invasive way of assessing liver fibrosis. A 2D-PAGE based proteomics study was used to identify potential fibrosis biomarkers. Serum from patients with varying degrees of hepatic scarring induced by infection with the hepatitis C virus (HCV) was analyzed. Several proteins associated with liver scarring and/or viral infection were identified. These proteins include the inter-?-trypsin inhibitor heavy chain H4 fragments, complement factor H-related protein 1, CD5L, Apo L1, and ?2GPI. Increased and decreased thiolester cleavage of a2M and Complement C3, respectively, was also detected. The concentrations of these novel biomarkers can be determined using an immunoassay where the concentrations would reflect the extent of fibrosis. A fibrosis scoring scale for each of the novel biomarkers is proposed.
